Is coffee good for you? Here we will talk about some benefits of coffee, particularly on weight loss and its effects on your metabolism.

Most commercial fat-burning supplements contain caffeine - a psychoactive substance that is most commonly consumed today.

Caffeine helps mobilize fats from your fat tissue and boost metabolism.

Coffee Carries Stimulants

Coffee beans contain several biologically active substances, and some of them find their way into the final drink. Some can even affect metabolism.

Caffeine: How much caffeine in coffee? Caffeine is the main stimulant in coffee, with 40 grams per 100-gram coffee.

Chlorogenic acid: This is a natural antioxidant compound found in coffee that may help slow carb absorption.

Theobromine: Coffee contains small amounts of theobromine, which is the main stimulant in cocoa.

Theophylline: This substance is present in both coffee and cocoa and has been found to be used for asthma treatment.

Among the abovementioned biologically active substances in coffee, caffeine is the most important as it has been studied thoroughly and has been found to be very potent at helping you stay active.  

This substance blocks an inhibitory neurotransmitter called adenosine, which boosts the firing of neurons and releases neurotransmitters like norepinephrine and dopamine, thereby making you feel more energized.

In fact, drinking coffee has been found to improve exercise performance by 11–12%, on average.

Coffee Can Help in Fat Metabolism

Containing caffeine, coffee can raise blood levels of the hormone epinephrine, also known as adrenaline, which prompts the breakdown of fats to be released into your blood.

However, it is important to note that a mere release of fatty acids into your blood does not help you lose fat; you also need to achieve a negative energy balance - a condition in which you burn more calories than you actually consume.

To achieve a negative energy balance, you may either exercise more, eat less, or take fat-burning supplements like caffeine.

Caffeine can also help increase your metabolic rate.

Coffee Can Help Boost Your Metabolic Rate

The total number of calories you burn at rest is called resting metabolic rate (RMR).

A higher RMR makes it easier for your to lose weight and allows you to eat more without having to worry about gaining weight.

Caffeine has been shown in studies to increase RMR by 3–11%. Additionally, larger doses have a greater effect.

Most of the increase in RMR stems from the increase in fat burning.

However, obese individuals experience this effect lesser than lean people.

In fact, caffeine has been shown in one study to increase fat burning by only about 10% in obese individuals and as much as 29% in lean people.

Additionally, the effect is greater in younger individuals and may decrease with age.

Long-term Effects of Coffee on Weight Loss

Although caffeine increases metabolic rate and boosts fat burn in the short term, people gradually become tolerant of its effects, and then it stops working.

Fortunately, coffee still finds a way to help you lose weight.  Aside from increasing the number of calories you burn and breaking down fats, it can also potentially reduce appetite and delay stomach emptying, thereby helping you eat less, leading to weight loss.

In fact, caffeine has been found in one study to have an appetite-reducing effect in men, making them eat less at a meal post caffeine intake.

Consuming caffeine 0.5–4 hours before a meal may affect appetite hormones, stomach emptying, and feelings of hunger.

However, some studies found no weight loss-inducing effects from caffeine ingestion.

So it can be deduced that the long-term effects of coffee or caffeine on weight loss may vary from individual to individual.

Plus, take note also that overconsumption of caffeine, i.e. ≥ 250mg, can increase blood pressure in some people.

Other Benefits of Coffee

Aside from improved metabolic rate, fat loss, and weight loss, there are several other benefits of coffee that you can enjoy.

Coffee contains several essential nutrients, such as manganese and potassium, riboflavin, magnesium and niacin, and pantothenic acid.

It is also an excellent source of antioxidants in the Western diet. In fact, many people have been shown in studies to get more antioxidants from coffee than from vegetables and fruits.  

What’s more, coffee may help improve your energy levels and reaction times, protect your liver, lower your risk of Parkinson’s disease, and fight depression, among others.

The Takeaway

Coffee can help boost your metabolic rate in the short term, but such effect reduces in long-term coffee drinkers because of tolerance.

Thus, coffee’s and caffeine’s long-term effects on metabolism and weight loss are yet to be studied and determined.

If you are drinking coffee to lose fat, then try to cycle your drinking habits, perhaps two weeks on and two weeks off, so as to prevent tolerance buildup.

Of course, there are several other benefits of coffee, including improved energy levels and reaction times and lower risk of type 2 diabetes.
